B Explanation: The SAN Volume Controller Performance Monitor does not store performance data for later analysis. Instead, its display shows only what happened in the last five minutes. Although this information can provide valuable input to help you diagnose a performance problem in real time, it does not trigger performance alerts or provide the long-term trends that are required for capacity planning. For those tasks, you need a tool, such as IBM Tivoli Storage Productivity Center, to collect and store performance data for long periods and present you with the corresponding reports. For more information about this tool, see Chapter 13,“Monitoring” on page 349.
